Analysis of SLC39A4 gene mutation in a patient with acrodermatitis enteropathica / 中华医学遗传学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To detect pathogenic mutation of the SLC39A4 gene in a male patient with acrodermatitis enteropathica (AE).</p><p><b>METHODS</b>Peripheral venous blood sample and clinical data from the patient and his parents were collected. One hundred unrelated healthy individuals were recruited as controls. All coding exons and flanking exon-intron sequences of the SLC39A4 gene were analyzed by PCR and direct sequencing.</p><p><b>RESULTS</b>The results revealed that the patient and his mother have both carried a novel frame-shift mutation c.1110InsG (p.Gly370GlyfsX47 to TGA) in exon 6. A novel nonsense mutation c.958C to T (p.Q320X) in exon 5 was also detected in the patient and his father and grandmother. This novel mutation was not detected in the unaffected family members and 100 unrelated healthy controls.</p><p><b>CONCLUSION</b>The novel frame-shift mutation c.1110InsG (p.Gly370GlyfsX47 to TGA) derived from the mother and nonsense mutation c.958C to T (p.Q320X) of the SLC39A4 gene derived from the father may underlie the disease in the patient.</p>
